Course Outline:
- Step-by-step procedures performed by an LTE User Equipment (UE) from initial power-on through data transfer and service utilization
- Introduction of the Evolved Packet System (EPS) network architecture, where each network node is described
- Discussion of the EPS registration procedure and how subscription data is utilized during initial cell selection
- In-depth discussion of the control messaging and parameter configuration of the various nodes and interfaces in EUTRAN and the Evolved Packet Core (EPC), which facilitate registration with the EPS network and the establishment of EPS bearers
- Discussion of how EPS bearers are utilized for transporting user plane application data to external networks
- How QoS support is achieved through the setup of dedicated EPS bearers
- Includes illustration of packet filters, packet marking, and charging to explain how user plane data flows through the EPS network
- Multiple PDN connectivity in EPS network
- Discussion of mobility in idle and connected states and description of measurement configuration, cell reselection, and handover for both intra-LTE and inter-RAT (UTRAN and eHRPD)
- Introduction of the concept of Circuit Switched Fallback (CSFB), whereby support for CS voice is achieved by redirection of a UE to an underlying UTRAN or 1xRTT network
